An optomechanical disk in its fundamental state of motion
The motion of a mesoscopic mechanical resonator can exhibit quantum behavior when cooled to very low temperatures. In particular, it can reach its ground state and cease to vibrate. Using light as a probe, the LIME team at the MPQ laboratory demonstrated that...
Watching gold switch between order and disorder
Researchers from Matériaux et Phénomènes Quantiques laboratory have directly observed, for the first time, a reversible phase transition between amorphous and crystalline states in ultra-small gold nanoparticles. Their findings reveal that the atomic structure of gold...
Exact low-energy duality in superconducting quantum circuits
The THEORIE team, in collaboration with Michel H. Devoret, has published a theoretical study in Physical Review Letters demonstrating an exact low-energy duality in circuits where a Josephson junction is coupled to a multi-mode environment. These systems exhibit a...
Multiphysics optomechanical sensing of a liquid on the micron scale
The LIME team at MPQ laboratory, in collaboration with CEA LETI in Grenoble, has published an article in Microsystems & Nanoengineering presenting an optomechanical platform for characterizing the rheological, optical, and thermal properties of fluids at the...
Biphoton state generation and engineering with bright hybrid III–V/silicon photonic devices
The QITE team at the MPQ Laboratory, in collaboration with STMicroelectronics, C2N, and INPHYNI, published a paper in Optica Quantum on the generation and engineering of two-photon states using III-V/SOI hybrid devices. Artist’s sketch of...
TUPHO, for large-scale production of integrated photonic circuits
The TUPHO project is an initiative that aims to bridge the gap between upstream innovation and large-scale production in the integrated photonic circuits (PICs) industry. It is led by Hamidreza Neshasteh and Ivan Favero, members of the Light and Mechanics team at MPQ...

On-Chip Ferromagnetic Resonance for van der Waals Heterostructures: Anisotropy and Damping of Cobalt Interfaced with Exfoliated 2D Materials
A collaboration between the technical hub, the clean room platform and the TELEM group at MPQ laboratory has developped a new experiment demonstrating that standard broadband ferromagnetic resonance can still be effective to probe the magnetization dynamics of “thin...
